Alcohol in the Body

1.Alcohol is taken into the body through the mouth.

This is called Ingestion

 *its use increases the risk of cancer of the mouth and esophagus

 2. Alcohol has no food value.

 No digestion takes place in the stomach. Some is absorbed into the bloodstream. The rest of the alcohol passes into the small intestine.

 * Alcohol irritates the stomach lining. The acute effects of heavy drinking, such as gastritis and bleeding peptic ulcers, are more likely in the adolescent.

 3. From the Small Intestines, most of the alcohol is absorbed rapidly directly into the bloodstream

 4. The Bloodstream carries the alcohol to all parts of the body.

(The brain is “bathed” in alcohol almost immediately)

 5. The Liver is the “Chemical Factory” of the body. It acts as a cleansing station to rid the body of poisons.

 The Liver removes alcohol from the blood. It breaks down the alcohol into carbon dioxide and water by a process called oxidation

 ***OXIDATION OCCURS AT A CONSTANT UNCHANGABLE RATE OF ½ OUNCE OF PURE ALCOHOL PER HOUR

 (about 1 standard drink per hour)

 What is a Standard Drink?

 12 ounces of Beer

 5 ounces of Wine

 1.5 ounces of liquor

 6. The Brain is the “Control Center” of the body.

The brain is “bathed” in alcohol almost immediately upon ingestion.

 Excessive amounts can cause the organs vital for life to stop functioning.

 Alcohol keeps passing through the brain until the liver has had enough TIME to remove all the alcohol from the bloodstream.

The brain is the organ most sensitive to alcohol. It affects judgment, learning, behavior, coordination and vision

Blood Alcohol Concentration

•The amount of alcohol in a person’s blood expressed as a percentage- legal limit for driving in WA is .08

•BAC depends on:

–Body weight

–Water content in body tissues

–Concentration of alcohol in beverage consumed

–Rate of consumption

–Volume of alcohol consumed

 

•Alcohol is a depressant- slows CNS

•Alcohol is an anesthetic- it numbs pain

•Proof= is the measure of the percentage of alcohol in the drink

•Alcohol percentage= ½ the proof

•80 proof whiskey= 40% alcohol

 •Wine= 12%-15% alcohol

•Beer= 2%-6% alcohol

•Ales= 6%-8% alcohol

Long Term Effects of Drinking

•Brain Damage

•Liver problems- Cirrhosis of the liver

    Liver tissue is destroyed and replaced with scar tissue

•Tolerance and Dependence

•Gastrointestinal tract

•Cancer

•Malnutrition

 

Short term effects of alcohol on the body depend on several factors:

•Amount of alcohol consumed

•Persons gender and size- BAC of a 130Ib person drinking 4 drinks will be higher than that of a 160Ib person

•Women have less of an enzyme that metabolizes alcohol, so it takes longer for the alcohol to be digested out of the system

•Food in the stomach

Parts of the Body Affected by Alcohol (short term)

•Brain

•Liver

•Blood vessels- blood vessels widen

•Heart- increases heart rate and blood pressure

•Stomach
